I don't know where you got the impression that art is taught to make people feel good. There are careers in art and it has a practical use.
Instead of diverting the argument into one on the discussion of art in the classroom, please advise what practical applications could come from learning creationism?
I view art and creationism the same in many respects. There is much art that does nothing of value except to its creator. That is the nature of some art. The same go's for creationism. Some people derive a great deal of comfort from that belief, just like some people derive a great deal of comfort from art. Why is it acceptable to denigrate one and not the other?
Put another way, why do you fear creationism? The nature of education is to teach all angles. Anyone who limits you to a single viewpoint isn't teaching at all, they are merely speaking at you. No one should fear creationism so long as evolution is taught as well. If there were only creationism being taught I would have the same viewpoint.
My daughter is 7 years old now and she is getting a hell of an education from me in the hard sciences, the soft sciences from her mom and regular school work at her private school. We fear nothing for her because she will have the tools to make a good decision no matter what comes her way.
That is how education should be.
Do you see the difference?
